Character glitch in animation blueprint

i’ve got this problem after i’ve made some modification in this animation blueprint, but i don’t know why this is happen.
when i set blend weights to 0, the character is normal but it’s not working the aimoffset when i aim down and up, when i set up the blend weights to 1, the character glitch and i don’t know why, i’ve seen some backup that i’ve made and it’s set to 1 without any problem.

image 1 → blend weights = 0

image 2 → blend weight = 1
